Learn about Ultra-High Performance Concrete for Prefabricated Bridge Element Connections

by

Ultra-high performance concrete (UHPC) can be used to create simple, strong, long-lasting connections needed for successful construction using prefabricated bridge elements (PBEs). Compared to many solutions in current use, UHPC allows for small, simple-to-construct connections that require less volume of field-cast concrete and do not require post-tensioning. The mechanical properties of UHPC also allow for redesign … Read more Learn about Ultra-High Performance Concrete for Prefabricated Bridge Element Connections

FHWA TechNotes on Bridge Construction Using Prefabricated Elements

by

FHWA’s Bridge Engineering Research Team in the Office of Infrastructure Research has released two new TechNotes focused on bridge construction using prefabricated elements.  Prefabricated bridge elements are assembled then connected onsite during bridge construction, and these connections often include the use of field-cast grouts.    These two TechNotes (FHWA-HRT-16-080 and FHWA-HRT-16-081) provide insight into test methods, key … Read more FHWA TechNotes on Bridge Construction Using Prefabricated Elements
